IMPROVEMENT IN MACHINES FOR TREEING BOOTS AND SHOES.

Specification forming part of Letters Patent N0. 200,979, dated March 5, 1878; application led February 2, 187s.

To all whom if may concern:

Be it known that I, WILLARD Corner, of Westborough,- in the county of .Worcester, in the State of Massachusetts, have invented a new and useful Machine for Treeing Boots and Shoes, of which the following is a specification:

The nature of my invention consists in organizing, in a single machine, a device of a jack for holding the boot or shoe and a mechanism for operating the rub-stick, the jack being adjustable to any desired position, allowing the boot or shoe to be turned so as to present any part to the action of the rub-stick, the rub-stick and its mechanism being so made that it can reach all parts of the boot or shoe, and that its motion and field of motion can be regulated at will by the operator while the machine is in motion.

The exact nature of my invention may be best understood by reference to the specification and drawings.

Figure 1 is a front elevation of my machine. Fig. 2 is a plan of the same. Fig. 3 is a rear elevation of the same. Fig. l,tis an end elevation of the same. Fig. 5 is an enlarged view of the rub-stick.

In my machine I mount the boot on a tree, in the usual manner; then I connect the tree to the jack-head E2, Fig. 1, by means of a rod or shaft that extends from the tree to which it is attached through the jack-head E2, in which position it is free to revolve, unless fastened in position by the hand-screw E5. The jackhead E2 swings on a pivot, E3, which attaches it to a standard extending upward from the base-plate E, Fig. 1. The lower end of the' swinging jack-head E2 has cut upon it some screw-threads, which engage with the screw E6, so that by turning the screw E6 by the hand-wheel E7 the jack-head may be swung back and forth, so as to raise or lower the front end of the tree.

The jack is fastened to the yielding table Dl by means of a flat-headed bolt and nut, El E9, said bolt passing through the base E of the jack and through slots d1 cl2. (See Fig. 2.)

The table D1 is attached by screws D3 Da D2 D3 and springs D2 D2 D2 D2, surrounding these screws, so that the table D1 yields to any considerable downward pressure, it, in fact, resting on the springs D2.

The lower table D rest on flat levers d d, and these levers again resting on the fulcrums d3 d3, said fulcrums being cross-bars attached to the frame of the machine.

The inner ends of the levers d d are attached by the straps G to a foot-lever, G, by means of which the entire table D Dl may be raised or lowered, and, through ratchet-plate G2, held at any desired elevation.

Owing to the fact that as a boot or shoe is revolved on the tree it presents a constantlychanging and highly-diversified series of positions, and as no two lots of boots offer the same contour to the rub-stick, it is necessary that the tree should not only be adjustable in every direction, but also that it should yield so far that while the rub-stick shall always be kept in full contact with the work, yet no damage may result to the boot or shoe which is bein'g operated upon. These effects, it will be seen, are fully attained by the combinations of adjustments and springs, as set forth above.

The rub-stick L2 (shown in Fig. 5) may be made in any desirable shape, and may be pivoted at l and held in position by the spring Z. This rub-stick L2 is attached,by the shank L', t0 the moving housing L3, said housing being attached by the bolt L, which passes through the guide-slot F1 F2, Fig. 1, into the sliding nut J2, (see Figs. 1, 2, and 3,) so that when J2 is made to slide it communicates its motion to the rub-stick housing L3.

The rub-stick end of the housing L3 is guided by a stud which slides freely in the slot F2, so that as the housing moves back and forth this end will rise and fall-that is, conform in its motion to the guide-slot F1 F2.

Motion is imparted to the sliding nut J2, which operates the rub-stick, by the crankdisk H, Fig. 3, on the rear face of which is a stud tted in a sliding block, which stud and block have a rotary motion about the center of the disk, and at the same time a reciprocating motion in the channel H2 in the swinging arm H1, to which it imparts a reciprocating motion. In the rear of the swinging arm Hl is formed a second channel, in which rotates the screw H4, onwhich a pivot-block traverses.

To this block one end of the link H9 is pivoted, While the other end is attached to the sliding block H2, Fig. 3. This block H2 carries a screwshaft, J1. Said screw-shaft J passes through the sliding block J2, in which it acts as a screw. The end of this shaft is provided with a spurgear, J, which engages the cylinder-gear J2.

From the above it may be seen that the block J2, which controls the position and motion of the rub-stick L2, may be adjusted to any relalrive position with the block H2 by means of the screw-shaft J1, which is actuated by the gears J and J2 and the crank J4. Thus the eld of motion of the rub-stick is adjusted in any position within the limits of the guide-slot F1 F2, Fig. 1.

To adjust the length of the stroke of the rubstick, the block H3, Fig. 3, is moved vertically by turning the screw H, (see Fig. 4,) which effect is produced through the bevel-gears H5 H, the shaft H7, and the crank X.

Having now described the construction and operation of my invention, I claim and desire to secure by Letters Patent- 1. In a boot or shoe treeing machine, the combination of the jack E E2 and yielding sup port or table D, all substantially as and for the purpose set forth.

2. The combination of' the yielding table D, the springs D2, screw-posts D3, and the plate D with the levers d, straps G1, and foot-lever, all operating together substantially as described, and for the purpose set forth.

3. The combination of the rub-stick L2 and its holder L3 with the guide-slot Fl F2, operating substantially as described, and for the purpose set forth.

4. In a boot-treeing machine, the combination of the block J2, the screw J1, the block H2, and gear-wheel J, al1 operating substantially as described, and for the purpose set forth.

5. In a boot and shoe treeing machine, the combination of the block H2, the link H9, the pivot-block H2, and the screwr H4 with the swinging arm H, gears H5 H6, and shaft H7, all operating substantially as described, and for the purpose set forth.

6. In a jack, the combination of the swinging part E2 with the adjusting-screw E5, substantially as described, and for the purpose set forth.

7. In a boot and shoe treeing machine, the rub-stick L2, having a pivoted or hinged joint, l, and spring l', substantially as described, and for the purpose set forth.
